Application led December 29, 1917. Serial No. 209,533.

To all whom t may concern Be it known that I, PETER BEAUSHENE, a citizenof the Dominion of Canada, residing at Renton, in the county of King andState of Washington, have invented new and useful Improvements inLawn-Mowers, of which the following is a specification.

This invention relates to lawn mowers, and has for one of its objectsthe provision of a machine of this character which is simple inconstruction, to operate with the desired smoothness and eiiiciency,being provided with means for raking and collecting the grass or othermaterial subsequent to being cut.

The invention embodies an apron attachment upon which the grass or othermaterial is raked subsequent to being cut, the apron being detachablyassociated with the machineJ to permit use of the latter with or withoutthe apron as desired.

The nature and advantages of the invention will be better understoodwhen the following detail description is read in connection with theaccompanying drawings, the invention residing in the construction,combination and arrangement of parts as claimed.

In the drawings forming part of this specification like numerals ofreference indicate similar parts inthe several views and wherein Figure1 is a front elevation of the machine constructed in accordance with myinvention.

Fig. 2 is a rear elevation.

Fig. 3 is a top plan view.`

Fig. 4 is a sectional view taken on line 4-4 of Fig. 1.

Fig. 5 is a sectional view taken on line 5-5 of Fig. 4.

Fig. 6 is a section taken on line 6-6 of Fig. 1.

Referring to the drawings in detail A indicates generally the body orframe of the machine, which embodies a base 10 from which rises at theopposite extremities thereof parall'el standards 1K1 which are'connected at their upper ends by a cross piece 12. The frame furtherembodies a pair of spaced substantially triangular shaped side pieces 13which are secured to the standards 11 and projecting rearwardlytherefrom. Projecting laterally from the standards 11 are stub shafts 14upon which are journaled the traction wheels l5. the lat-y ter beingpreferably provided with a roughened peripheral surface 16. A plate 17is secured in any suitable manner to the base 10 and forms acontinuation of the latter, the plate providing a support for the xedblade 18. Suitably secured to the base 10 is a second plate 19 overlyingthe fixed blade 18, and interposed between the latter and the projectingedge of the plate 19 is a movable cutting blade 2O arranged toreciprocate relative to the ixed blade. The blades 18 and 20respectively are of usual construction.

For the purpose of imparting reciprocatory movement to the blade 20, Iemploy a vertically disposed shaft 21, arranged adjacent and inparallelism with one of the standards 11, the said shaft having' oneextremity journaled in the upper part of the adjacent shaft 14, whilethe opposite extremity of the shaft is reduced as at 22 and journaled inan apertured lug 23 projecting laterally from the cross piece 12 of theframe. Fixed to the reduced extremity of the shaft 21 is a disk 24 tothe upper surface of which one end of a link 25 is eccentricallyconnected, the opposite extremity of said link being suitably secured toa slide 26 reposing upon the cross piece 12 of the frame. Fixed to theshaft 21 is a cog wheel 27 which meshes with a ringA gear 28 carried byone of the wheels 15, and manifestly as the wheels 15 are rotated overthe ground, the shaft 21 is also rotated with a resultant reciprocatorymovement imparted to a slide 26. The slide 26 is provided with spacedlongitudinally disposed slots 29 which receive headed fastening elements30 which serve to maintain the slide operatively positioned upon thecross piece 12 of the frame. Projecting forwardly from one of thelongitudinal edges of the slide is a pin 31 which is received within anelongated slot 32 of a rock arm 33, the latter being fulcrumed upon oneof the standards 11. The lowermost extremity of the arm 33 is arrangedbetween spaced lugs 34 rising from the movable cutting blade 20 at oneend thereof. The lower extremity of the arm is also slotted as shown, toreceive the pin carried by the lug 34 which serves to hold the partsoperatively associated. Obviously as the slide 26 is moved across theframe A, rocking movement is imparted to the arm 33 which in turnreciprocates the cutting blade 20 in the usual manner.

nected by a transverse rod 35 which is used to prevent spreading oftheside piecesand to increase the strength o'f the machine generally. Therear edge of each side piece is provided with a vertically disposeddovetailgroove 36, and these groovesare adapte'd'to receivethe posts 37of similar cross sectional configuration'lrising-from the oppositeextremities of a shaft 38 upon which is loosely mounted a ground rollery39. rlhe posts37 are -pro-vided'with a' series of openli1i-igs49-one-ofw'hich'isfadap'ted `to register with an opening in the. rearlwallv of the groovesY 36, fo'rrthe receptionofa set screw 'oroth'ervsuitable fastening element- 41 which holdsthe posts fixedrelativelyv tox lthe side members 13. This construction Obviouslyprovides 'for' an adjustment of the ground roller' 39 'in afverticaldirection sol as to -vary the I distance between the cutting blades andthe surfaceof the` ground as will be readily understood. lSuitablysecured to the side members 135 of' theframe-are relatively' shorthandles 4'2 to vwhich auxiliary handles of any-desiredflengtli (notshow-n)y maybe attaehed.v

The .machine is primarily intended for cutting grass-althoughits use isnotlimited in this capacity. With a view of collecting thel grass `orother material subsequent' tobeingJc'u-t,Iprovide'an-apron 43 which isdisposed between they side pieces 13 and unitedly defines therewith acompartment for 4thereception of the cuttings. It is my purpose toprovide' a detachable connection between the apron 43 andA the frameofthe machine-to permit the latter to be'used with orwithout the apron asdesired. -llith this end v inl view I provide the rear edge ofI the base10l with a longitudinally extending groove 44 which receives one end ofthe apron 43. As shownthe apron 43 is curved longitudinally' in anupward direction whereby the rear end of the apron is positionedbetweenthe transverse rod 35'v and the ground roller 39. Swingingly associatedwith-thisfen'd' of theapron are hook-like'elements 45 which are adapted'to y engage` the stationary hooks 46 secured to the upper edge of the's'i'depieces 13. Thehooks 45 co- Operate with' the hooks 46 to maintainthe apron fixed in its proper position upon the machine when its use isdesired, it 'being only necessary to disengage the hooks 45 fromtheahooks 46 to remove the apron from the machine, which can beconveniently done by simply removing' the apron from the1groove44. Y

The sideV pieces' 13 are provided With alined' recesses 47'"constituting 4bearings yfor theopposite ends of a shaft .48 formin'gpartof a rake. Plates 49 are suitably securedv to thesi'degpieccsll coveringthe recesses 47 to prevent accidentall separation of the shaft 48Ifrom'it's bearings or derangement thereof. The plates may be readilyseparated from the side pieces when it is desired to remove the rake forany purpose whatsoever.. Radiating from the shaft 49 are a plurality ofarms 50, the arms being arranged invspaced pairs, and secured to-each.pair is a transverse strip 51 from one edge of' which project a series0f fingers 52. These associated parts define a rake which when themachine-is-oper-atedxserves-to rake `the cuttings-upon thevapron- 43' aswill be readily apparent. @ne endofff the/'shaft 48 projectsbeyondr theadj acentv Vside member 13 .and lhas securedthereto -a small cog ywheel53"*over which, and'- a-f-relativelyl large cog wheel15'4-secured'to theground wheel 15, is ytrained an' endless chain, whereby rotary motionis'ii-npartedi to the shaft 48'1as the ground wheels 1'51 are movedover-the surface; thus operating the-:rakewith the travel of themachine.The machine in' addition to being positive .inl operatioir is-light anddurable: The` ground'wheel-s 15 together with their associated parts areprotected from injury byv comingin-contact with obstacles, bylmetallicguards partly encircling-the wheels 15, vthe guards-being provided withflanges 56 which are* secured tov the standards'1'1.-

While it is believcdrthatfrom the foregoingv deseriptionlthenature andadvantages ofS the invention will be readily apparent, I desire' to haveVit understood that what' is herein shown andIdescr-ibedis merelyillusthe frame and having connection with the oppositeend of said7 arm,and means' for impartingn motion to said slidefromr one of' said wheelswhereby toV reciprocate said movable blade.
